ing cantalivers supporting at their outer ends an I-beam upon which the trucksupporting rail is mounted.

A further object is to provide improvements of the character stated which embody in their construction, simplicity, durability, and the maximum of strength to withstand strains and stresses to which such parts are necessarily subjected.

With these and other objects in view; the invention consists in certain novel features ,zontal transverse section on the line 41 of Fig. 3. Fig. 5 is a view in vertical section on the line 55 of Fig. 3/

1-1 represent longitudinal girders supported by transverse girders 2 located at the upper ends of uprights 3, and said longitudinal girders are located parallel to each other, spaced apart, and strengthened by any suitable sway bracing 4 to hold the girders properly spaced and to strengthen them against lateral strains and stresses.

The longitudinal girders 1 are alike, and the description hereinafter of one will apply alike to both. Each longitudinal girder 1, at its upper edge, is provided with a pair of longitudinally positioned angle bars 5 constituting the upper cord of the beam, and between which at regular intervals, gusset plates 6 are secured The lower cord of the longitudinal beam is formed by a pair of angle bars 7 secured at opposite sides of a longitudinal plate 8, and the gusset plates 6 and longitudinal plate 8 are connected by diagonal struts 9 and vertical struts 10. These struts 9 and 10 are preferably angle bars, and the vertical struts 10 are arranged in pairs and constitute points of intersection along the girder. At such points of intersection, I provide by improved laterally projecting cantalivers 11, the description hereinafter of one applying alike to all. Be tween the "ertical angle bar struts 10, at the points of intersection, I secure triangular shaped plates 12. These plates 12 are preferably shaped. as shown, that is, their lower edges are, horizontal and their upper edges are inclined downwardly from their inner to their outer ends. 7

.The upper and lower edges of the plates 12 are strengthened by angle bars 13 and 14 respectively, which are securely riveted to the plates and to the vertical struts 10 as clearly shown in Fig. 3. At the outer ends of the plates 12, I secure angles 15 which are also secured to the webs of longitudinal I-beams 16, and said I-beams are secured by plates 17 to the angle bars 7 forming the lower cord of the longitudinal beam. These plates 17 are also triangular in shape with their wider ends located under and secured to the bars 7 as shown clearly in Fig. 4, and such plates serve to prevent any lateral movement of the cantaliver or longitudinal movement of the I- beam. The I- beams support on their upper edges, rails 18 to receive the double flanged wheels 19 of trucks 20 supporting the cars 21 suspended therefrom.

The longitudinal girders 1 are connected to the transverse girders 2 by means of shear plates 22. These shear plates are located at opposite sides of the transverse girders and extend between the parallel angles 6 constituting the upper cord of the longitudinal 100 transverse girders 2, are securely riveted to 105 the bars 6 and 7. They are strengthened at their edges by angle bars 23, and are also connected to the .ioogitudinal plates 8 by means of diagcnal struts 24. In other Words, the plates 22 are positioned between 110 Patented May 11, 1915. v

the pairs of angle bars 6 and 7 and constitute not only coupling means for the longitudinal and transverse girders, but also strengthen both the longitudinal and the transverse girders, and insures a rigid juncture of the parts.

Various slight changes might be made in the general form and arrangement of parts described without departing from my 1nvention, and hence I do not limit myself to horizontal plates below the cantalivers se-' cured to the girder, substantially as described.

2. In a suspension railway, the combination with a longitudinal girder, of laterally projecting cantalivers on the girder, a longitudinal rail supporting beam secured to the cantalivers and means connecting the beam with the bottom of the girder, sub stantially as described.

3. In a suspension railway, the combination with a longitudinal girder, of laterally projecting cantalivers on the girder, a longitudinal rail supporting beam secured to the cantalivers, and horizontally positioned plates connecting the lower edge of the beam with the lower edge of the longitudinal girder, substantially as described. 7

4. In a suspension railway, the combination with a longitudinal girder, of cantali vers projecting laterally from the girder, an I-beam secured to the outer ends of the cantalivers, a rail supported upon the I-beam, and plates connecting the I-beam with the bottom of the girder below the cantalivers, substantially as described.

5. In a suspension railway, the combination with a longitudinal girder consisting of upper and lower parallel angle bars connected by vertical and diagonal angle bar struts, said vertical angle bars arranged in pairs, of laterally projecting vertically positioned plates secured between the pairs of vertical struts, and rail supporting beams secured to the outer ends of said plates, substantially as described.

6. In a suspension railway, the combina said vertical angle bars arranged in pairs, of laterally projecting vertically positioned plates secured between the pairs of vertical struts, angle bars secured to the plates at their upper and lower edges at opposite sides, angles secured to the opposite sides of the plates at their outer ends, and a rail supporting beam secured to the last mentioned angles, substantially as described.

7. Ina suspension railway, the combination with a longitudinal girder consisting of upper and lower parallel angle bars connected by vertical and diagonal angle bar struts, said vertical angle bars arranged in pairs, of laterally projecting vertically positioned plates secured between the pairs of vertical struts, angle bars secured to the plates at their upper and lower edges at opposite sides, angles secured to the opposite sides of the plates at their outer ends, a rail supporting beam secured to the last-mentioned angles, and plates connecting the lower face of the beam with the lower face of the girder and located below the firstmentioned plates, substantiallyv as described.

8. In a suspension railway, the combination with uprights, transverse girders connecting the uprights, longitudinal girders secured to and suspended from the transverse girders, cantalivers secured to the longitudinal girders, I-beams secured to the cantalivers, and rails supported upon the I-beams, substantially as described.

9. In a suspension railway, the combination ivith a plurality of transverse girders, of parallel longitudinal girders, each longitudinal girder consisting of upper and lower parallel angles, struts connecting the angles, shear plates secured between the angles and connecting thesame to the transverse girders, and laterally projecting rail supports on said girders, substantially as described.

10. In a suspension railway, the combination with a plurality of transverse girders, of parallel longitudinal girders, each longitudinal girder consisting of upper and lower parallel angles, struts connecting the angles,
